d a t a sh eet product speci?cation 2002 mar 04 integrated circuits 74ALVC574 octal d-type flip-flop; positive edge-trigger; 3-state
2002 mar 04 2 philips semiconductors product speci?cation octal d-type ?ip-?op; positive edge-trigger; 3-state 74ALVC574 features wide supply voltage range from 1.65 to 3.6 v complies with jedec standard: jesd8-7 (1.65 to 1.95 v) jesd8-5 (2.3 to 2.7 v) jesd8b/jesd36 (2.7 to 3.6 v). 3.6 v tolerant inputs/outputs cmos low power consumption direct interface with ttl levels (2.7 to 3.6 v) power-down mode latch-up performance exceeds 250 ma esd protection: 2000 v human body model (jesd22-a114-a) 200 v machine model (jesd22-a115-a). description the 74ALVC574 is a high-performance, low-power, low-voltage, si-gate cmos device and superior to most advanced cmos compatible ttl families. the 74ALVC574 is an octal d-type flip-flop featuring separate d-type inputs for each flip-flop and 3-state outputs for bus oriented applications. a clock (cp) input and an output enable ( oe) input are common to all flip-flops. the eight flip-flops will store the state of their individual d-inputs that meet the set-up and hold times requirements on the low-to-high cp transition. when oe is low, the contents of the eight flip-flops is available at the outputs. when oe is high, the outputs go to the high-impedance off-state. operation of the oe input does not affect the state of the flip-flops. the 574 is functionally identical to the 374, but the 374 has a different pin arrangement. quick reference data gnd = 0 v;

integrated circuit packages (document order number 9398 652 90011). there is no soldering method that is ideal for all surface mount ic packages. wave soldering can still be used for certain surface mount ics, but it is not suitable for fine pitch smds. in these situations reflow soldering is recommended. re?ow soldering reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. typical reflow peak temperatures range from 215 to 250 c. the top-surface temperature of the packages should preferable be kept below 220 c for thick/large packages, and below 235 c for small/thin packages. wave soldering conventional single wave soldering is not recommended for surface mount devices (smds) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. to overcome these problems the double-wave soldering method was specifically developed. if wave soldering is used the following conditions must be observed for optimal results: use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. for packages with leads on two sides and a pitch (e): C larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; C smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves at the downstream end. for packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves downstream and at the side corners. during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. typical dwell time is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. manual soldering fix the component by first soldering two diagonally-opposite end leads. use a low voltage (24 v or less) soldering iron applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c. 2002 mar 04 16 philips semiconductors product speci?cation octal d-type ?ip-?op; positive edge-trigger; 3-state 74ALVC574 suitability of surface mount ic packages for wave and re?ow soldering methods notes 1. all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . 2. these packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. 4. wave soldering is only suitable for lqfp, tqfp and qfp packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. wave soldering is only suitable for ssop and tssop packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. package soldering method wave reflow (1) bga, lfbga, sqfp, tfbga not suitable suitable hbcc, hlqfp, hsqfp, hsop, htqfp, htssop, sms not suitable (2) suitable plcc (3) , so, soj suitable suitable lqfp, qfp, tqfp not recommended (3)(4) suitable ssop, tssop, vso not recommended (5) suitable 2002 mar 04 17 philips semiconductors product speci?cation octal d-type ?ip-?op;
